Graying hair is a hallmark of aging, often considered an inevitable part of growing older. However, recent research from Nagoya University in Japan led by Masashi Kato and Takumi Kagawa suggests that an antioxidant might suppress this process. The researchers identified luteolin, an antioxidant found in vegetables including celery, broccoli, carrots, onions, and peppers, as being a potential anti-graying agent. Their findings pave the way for potential applications in human hair care.

The researchers’ study focused on three antioxidants—luteolin, hesperetin, and diosmetin—to assess their anti-graying effects in mice that were bred to go gray like humans...

Scientists uncover link between the nervous system and stem cells that regenerate pigment. Scientists have found evidence to support long-standing anecdotes that stress causes hair graying. Researchers found that in mice, the type of nerve involved in the fight-or-flight response causes permanent damage to the pigment-regenerating stem cells in the hair follicle. The findings advance knowledge of how stress impacts the body, and are a first step toward blocking its negative effects.
